Yes, Shun improves on it (testing voting up comments). Umihara Kawase DS actually provides a faithful port of both games, if you are looking for your complete grappling hook girl-on-fish experience on the move.

A faithful port of Outrun 2 (or a stripped down version of Coast 2 Coast). It lacks the additional single-player modes, and is currently no longer available to download since the Ferrari licence expired in 2010. But still, it's a perfect, smooth little game that is always a pleasure to play.
